GEORGE FULLARTON TAYLOR, OF LONDON, ENGLAND.

Specification of Letters Patent.

Patented Nov. 25, 1919.

Application filed April 11, 1919. Serial No. 289,319.

To all whom it may concern.-

Be it known that I, Gnonon FULLARTON TAYLOR, a subject of the King of Great Britain, residing at London, England, have invented certain new and useful Improvements in the Construction of Multiple-Roll Calender or Ironing Machines, of WlllCh the following is a specification.

The object of this invention is to construct a multiple roll calender or ironing machine in which the calendering or ironing is more efliciently performed, and the machine more convenient to work, the erection of same being also more easily accomplished.

For the purpose of this invention I position the rolls and concave beds in two inclined planes or curves the lower beds of which meet or have a separate bridge piece positioned between the two adjoining beds.

My invention will be clearly understood from the diagrams shown on the annexed drawings and in which Figure 1 is a section of eight rolls positioned in two planes and their beds, the beds having curved bottoms.

Fig. 2 is a section of eight rolls positioned in two planes and their beds the bottoms of the beds being so constructed that when conjoined form a smooth surface against which the articles being calendered can be passed by aprons in the well known manner.

In both figures the rolls A and beds B are positioned in two inclined planes with the lower beds meeting.

Steam is admitted to the two outside or upper beds B and travels throu h the beds toward the center or lower beds where it drains away.

The rolls A are capable of being raised en masse or singly, or in sections, as is well known, and all of the rolls are connected together by suitable gearing to revolve same at uniform speed and in the same direction and such driving may be through one pulley or a number of pulleys according to whether all the rolls are in gear together or in sections.

By this invention the article to be calendered is subjected to the greatest heat at its exit from the machine and in consequence is more erfeotly acted upon and more highly finisl ied.

The frame carrying the rolls, beds, gear and other mechanism may be as a whole, or in sections bolted together.

In all multiple roll calenders 0r ironing mach nes irrespective of the method of coupling up of the steam pipes, the tendency 15 for the whole of the condensation including that from main steam pipes leading to machlne, to find its way to the last beds over which the material is passed, the result being a lowering of the temperature, whereas, in those very beds, it is essential that the highest temperature be maintained. Now by this invention this feature of proyiding a high temperature at the last beds is malntained, and with the preferred con.- struction of machine, the wet, and therefore limp material by its passage over the first beds, which are arranged in a descending plane or curve, has derived the rigidity necessary to pass up the other beds which are arranged on an ascending plane or curve.

By this invention the machine is kept at a more convenient height so that the trestles on which the feeders stand may be dispensed with and the finished work is delivered at the proper height for easy handling by the folders. I

What I do claim as my invention and desire to secure by Letters Patent, is

A multiple roll calender or ironing machine with the rolls and concave beds arranged in two inclined planes or curves with the lower beds adjacent to each other, substantially as described and as shown on the annexed drawing.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GEORGE FULLARTON TAYLOR.
